Abstract
Power conversion equipment, such as power conditioning systems (PCSs), is known to generate conducted disturbance in a broad frequency range. Recently, the power capacity of the equipment has become larger because of the efficient use of them, and the conducted disturbances occur in the frequency range from 2 kHz to 9 kHz, where no measurement method and limit levels are regulated. In this paper, the design procedure and development of four types of artificial mains network (AMN) are studied in order to measure conducted disturbances and establish a reproducible measurement method that works in the frequency range from 2 kHz to 30 MHz. The impedance characteristics, isolation characteristics, and voltage conversion factor of each AMN are evaluated in both a circuit simulation and measurement to see if they can meet the required characteristics. As a result, it was found that the developed AMNs have a good agreement with the required characteristics.
